How do spiders find pages
  • robots or spiders follow links
  • Follow standard html links
  • DO NOT follow image maps, java animated menus,
    etc.
  • Therefore you need standard links to all pages
    in your site
  • Ideally include a SITEMAP.html file
  • EdSeek.org functional sitemap
  • www.shiloh.k12.il.us - main navigation menu

10
Categorized How?
  • The search engine software parses and reads all
    TEXT in the page (script/comments ignored)
  • It assigns priorities to the words
  • based on location in page
  • Title, Header section, Body section
  • based on number of times it is used
  • based on proximity of requested words to each
    other
  • Priority is given to Meta-Tags

11
Description Meta-Tag Example
  • lthtmlgt
  • ltheadgt
  • lttitlegtSmithsonian Institutionlt/titlegt
  • ltmeta NAME"description" CONTENT"The Smithsonian
    Institution is composed of sixteen museums and
    galleries and the National Zoo and numerous
    research facilities in the United States and
    abroad."gt
  • lt/headgt

  • lthtmlgt
  • ltheadgt
  • lttitlegtIllinois Technology Conference for
    Educators IL-TCElt/titlegt
  • ltmeta name"keywords" content"education,
    educators, educational, youth, conference,
    opportunities, improve, alternative, program,
    training, equipment, illinois, technology, ideas,
    schools"gt

Taking Controlling of which Pages are Indexed
  • ROBOTS.TXT file
  • Placed at root of Webserver
  • Or start in any folder

14
What is invisible to search engines?
  • Images (use alt tags)
  • Script (Java etc, some Image Maps)
  • Comments/Scripts
  • PDF DOC files are not easily indexed
  • Dynamic generated pages from Databases

Seekology 101 Introduction to Seekology
A Primer for Uber-Geeks, Alpha-Geeks, Neo-Geeks
and Non-Geeks Who Seek
18
Enlightenment No. 1
Nothing is available on the global network (web)
unless someone puts it there.
19
Enlightenment No. 2
If you put something on the global network and
dont tell anyone that its there, it might as
well not be on the global network.
20
Enlightenment No. 3
The most fundamental unit of information on the
global network is the file.
21
Enlightenment No. 4
The most fundamental method of accessing the most
fundamental unit of information is the hypertext
link.
22
Enlightenment No. 5
Humans access units of information by following
hypertext links using a process colloquially
called clicking.
23
Enlightenment No. 6
Web servers are software programs designed to
listen and respond to requests for files (clicks)
from clients on the global network.
24
Enlightenment No. 7
If it cannot be clicked, it probably cannot be
located by the average human user, unless one
knows the exact location (URL or address).
25
Enlightenment No. 8
Search engines consist of 2 separate software
programs crawlers and indexers
26
Enlightenment No. 9
Crawling is done by software programs called
robots (aka spiders and spidering bots).
27
Enlightenment No. 10
Robots work the same way humans dothey click
on hypertext links and follow them from file to
file.
28
Enlightenment No. 11
If there is no hypertext link to a file on a web
server, a robot cannot find that file. Links
on your home page are your key to seekology
enlightenment
29
Enlightenment No. 12
Even if a robot finds a file on the web, it may
not be able to parse (read) it.
30
Enlightenment No. 13
Basic spidering robots can read ASCII. Only
the most advanced robots can read .doc, .xls,
.rtf, .pdf, etc.
31
Enlightenment No. 14
Unless your web server publishes indexes of
files, any file that is not the target of a
hyperlink is invisible to robots
32
Example of Enlightenment No. 15
This is how one brand of web server shows a file
index
33
Enlightenment No. 16
The indexing software component of the search
engine parses files and stores keywords in a
database on the server.
34
Enlightenment No. 17
Your interaction with the search engine is in the
form of a keyword search of the database, from
which it creates pages of hyperlinks to the files
that contain the keywords along with a brief
listing of what those files contain.
35
Enlightenment No. 18
The robot and indexing software are designed to
pay special attention to text found within meta
tagged brackets in the header area of web
pages. ltmetagtinfo lt/metagt
36
Enlightenment No. 19
Search Engines are not intelligent.
37
Enlightenment No. 20
Search Engines are only as effective as the
organization of the global network allows them to
be.
38
Enlightenment No. 21
When material is placed on your web, make sure
there is a clickable path to find it.

Seekology 380 Optimization Strategies Beyond
the Primer
Enlightenments You Can Use on Monday.
40
Enlightenment No. 22
Use either the web servers automatic indexing
system or a tool such as dir2html to create
hyperlinked indexes of files.
41
Enlightenment No. 23
Publish in ASCII when possible.
This can include plain text, html, asp, php, or
other text-based coding
Advantages small, easily parsed, no plugins
42
Enlightenment No. 24
Use META-tags abundantly for high-profile
documents.
META-tag Generators make this easy.
43
Enlightenment No. 25
Use ALT attributes to describe graphics that
have valued context.
